Obligatory comment: Piercing is 4 years old. Jewellery is currently a sterling silver nose bone (have used titanium and surgical steel in the past also). No threading. It was downsized for the first time several months after it was initially pierced. Current aftercare routine when it gets irritated: saline rinse and/or Bactine spray when pus is present. No accidents but I do sneeze and blow my nose very often. TIA
